211:(ITU) created country codes for international dialing, first introduced in 1960 for Europe and expanded globally in 1964. Numbers were typically allocated by landmass and then subdivided by the capacity of each network at the time.

In 2003 the eighth edition of the Standardisation Agreement (STANAG) adopted the ISO 3166 three-letter codes with one exception (the code for Macedonia). With the ninth edition, NATO is transitioning to four- and six-letter codes based on ISO 3166 with a few exceptions and additions
